Electronic leak detection in Langley Vale: what you get
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. The results come in a report with photos. We survey single-ply roofs, commercial flat roofs and liquid-applied waterproofing, and the problems we’re asked to look at most are new roofs to check before paving or planting and a flat roof leak that can’t be traced.
Older buildings in small places like Langley Vale may be listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
We write the report in plain English, so it makes sense without any roofing background. Photographs show what each point refers to, and recommendations are put in order of urgency where relevant.

Landlord and commercial surveys in Langley Vale
An agent can book and manage the survey for a landlord, and the report can go to both. We agree a time with the tenant beforehand.
Landlords and agents in Langley Vale book surveys as well as householders. The report gives you a dated record of the flat roof membrane, with photographs, useful for planning maintenance.
Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
A DIY look is useful, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.

What else we do in Langley Vale
What a survey costs
All our prices include VAT. The things that change the price are:
- The size of the roof
- Whether it’s a home or a commercial building
- The number of roofs, including extensions and garages
- How complicated the roof is, with its valleys, chimneys and parapets
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
What to tell us when you get in touch
When you call or email, these details help:
- Where water is showing inside, if it is
- The kind of building and roof involved
- The address and postcode of the property
- Pictures of the roof from a safe spot, if you have them
To book a survey, ring 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.
What happens on the day
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, take photos as we go and make notes for the report. It usually takes a length of time set by the roof’s area and construction, which we’ll explain when we quote. Around Langley Vale, older homes can have small or awkward roof spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.

Advice
Electronic leak detection in Langley Vale: local notes
Fitznells Manor, about 3.2 miles north, is one of the historic houses in the wider area around Langley Vale. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. In Surrey, older roofs are frequently handmade clay tile, with tile-hanging on many upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
Take an older house close to St Stephen On The Downs: flat-roofed rear additions and dormers added over the years are worth checking. Anyone responsible for a site like The Vale Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. For businesses in and around places such as The Ashley Centre, a flat roof over a business is out of sight and out of mind until it leaks.

What we look for on each type of roof
Bituminous membranes
Many flat roofs use bitumen-based membranes. Whether ELD suits them depends on the build-up.
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Why act early in Langley Vale
Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. Where a roof is exposed, as many are in small places like Langley Vale, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

FAQs for Langley Vale
Does a conservation area affect roof work in Langley Vale?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Will you come out to Langley Vale?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Just mention lanes, gates or anything else about the route as you book.
Does the weather affect the survey?
Light rain is usually fine; heavy rain and wind are different. In high wind or heavy rain, a drone can’t fly and access may not be safe, and we’d agree another day.
What’s in the report?
It sets out what we found, why it matters and what we recommend, with photos throughout. It also says if any part of the roof couldn’t be seen safely.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
What insurance do you have?
Our cover is professional indemnity plus public liability, and details are available on request.
Can you test a green or ballasted roof?
On some roofs, yes. What sits on the membrane affects the method so we look at the roof first.
